Chapter 2.
ANSI
The TallyGenicom im ple m entation of ANSI X3.64 is the native control protocol for the 7265
printer, as it is for a variety of other TallyGenicom impact matrix printer families. The control
functions presented here are a superset of ANSI control sets familiar to our customers. For the
most part, ANSI drivers written for other TallyGenicom printers should only need to be modified as
features introduced on the 7265 Series printers are exercised. Examples of such new features
include user-defined formats, alternate paper paths, user-defined character substitutions, and
remote selection of emulations.
Enabling the application to select among emulations provides access to some of the 7265
features not supported in emulated products. Toward this end, the printer can be commanded to
maintain the current status of fonts, pitches, tabs, margins and so forth across emulation
changes. Although some minute differences due to translations from, say, columns to decipoints
may be discernible when switching from one emulation to another, the printer is quite predictable
when switching from another emulation to ANSI and then back again.
The 7265 is a decipoint machine. Locations and dimensions such as tabs, margins, absolute and
relative positions, and form lengths are described in ANSI control sequences in units of 1/720
inch. If you have the choice of describing your page in one or another of the supported
emulations, consider that ANSI gives you more flexible control of locations of objects on the page.
In this chapter we include spaces between characters in escape sequences for clarity. ESC H,
for instance, is easier to read than is ESCH. Where the space character forms a component of a
control sequence, then it is designated by <SP> .
Listed below are the control codes interpreted by this printer, along with page numbers where you
can find detailed descriptions.
